Abstract
Description
L'invention est du domaine des cycles, et elle a pour objet une bicyclette. The invention is in the field of cycles, and it relates to a bicycle.
On rappelle qu'une bicyclette est globalement constituée par un cadre supportant lieu une selle, un guidon, un couple de roues, dites respectivement avant et arrière, et un pédalier, le pédalier et la roue arrière étant chacun équipé d'au moins une roue dentée coaxiale, dite respectivement plateau et pignon, ces derniers étant reliés l'un à l'autre par une chaîne de transmission équipée de moyens tendeurs en vue de l'entraînement en rotation de la roue arrière à partir du pédalier. It will be recalled that a bicycle is generally constituted by a frame supporting a saddle, a handlebar, a pair of wheels, called front and rear respectively, and a crankset, the crankset and the rear wheel each being equipped with at least one wheel. coaxial toothed, called respectively chainring and pinion, the latter being connected to each other by a transmission chain equipped with tensioning means for the purpose of driving the rear wheel in rotation from the crankset.
Le but de l'invention est de proposer une bicyclette permettant au cycliste de prendre confortablement une position naturelle en correspondance avec les efforts qu'il a à fournir en fonction du terrain, et notamment de la déclivité de ce dernier. The object of the invention is to provide a bicycle allowing the cyclist to comfortably take a natural position in correspondence with the efforts he has to provide depending on the terrain, and in particular the gradient of the latter.
L'idée mère de l'invention a consisté à équiper la bicyclette de moyens pour rapprocher et éloigner le pédalier de l'axe de rotation de la roue arrière, de telle sorte que le cycliste puisse déplacer le pédalier suivant l'axe de progression de la bicyclette pour lui permettre d'ajuster sa posture en fonction des efforts qu'il a à fournir. The main idea of the invention consisted in equipping the bicycle with means for bringing the crankset closer and further away from the axis of rotation of the rear wheel, so that the cyclist can move the crankset along the axis of progression of the bicycle to allow him to adjust his posture according to the efforts he has to provide.
Une forme privilégiée de réalisation des dits moyens pour éloigner et rapprocher le pédalier, consiste à relier le pédalier et la selle par un bras, celuici étant articulé en pivotement sur le cadre et étant équipé de moyens de durcissement de son mouvement de pivotement, et de ce fait déplacer le pédalier sous l'effet d'une poussée exercée naturellement par le cycliste, lorsque celui-ci bascule son corps pour prendre une position adaptée aux efforts qu'il a à fournir. A preferred embodiment of said means for moving the pedalboard apart and closer, consists in connecting the pedal box and the saddle by an arm, this being pivotally articulated on the frame and being equipped with means for hardening its pivoting movement, and this makes the pedal move under the effect of a push exerted naturally by the cyclist, when the latter rocks his body to take a position adapted to the efforts he has to provide.
L'invention va être décrite en relation avec les figures des planches annexées, dans lesquelles
la fig.1 est une illustration d'une forme préférée de réalisation d'une bicyclette de l'invention,
la fig.2 est un détail en coupe longitudinale d'une même bicyclette,
les fig.3 et 4 d'une part, et 5 et 6 d'autre part illustrent respectivement des formes alternatives de réalisation d'une bicyclette de l'invention.The invention will be described in relation to the figures of the attached plates, in which
fig.1 is an illustration of a preferred embodiment of a bicycle of the invention,
Fig. 2 is a detail in longitudinal section of the same bicycle,
fig.3 and 4 on the one hand, and 5 and 6 on the other hand respectively illustrate alternative embodiments of a bicycle of the invention.
Sur les figures, la selle 2 et le pédalier 4 d'une bicyclette sont reliés par un bras 6 articulé en pivotement sur le cadre 8, de manière à ce que le cycliste puisse spontanément éloigner et/ou rapprocher le pédalier 4 de la roue arrière 10, lorsqu'il prend naturellement une position vers l'avant ou vers l'arrière de la bicyclette en fonction de la nature du terrain, et de ce fait des efforts qu'il a à fournir. In the figures, the saddle 2 and the crankset 4 of a bicycle are connected by an arm 6 pivotally articulated on the frame 8, so that the cyclist can spontaneously move and / or bring together the crankset 4 of the rear wheel 10, when it naturally takes a position towards the front or towards the rear of the bicycle depending on the nature of the terrain, and therefore the efforts it has to provide.
Selon une première forme de réalisation, représentée sur les fig.1,2,5 et 6, le bras 6 est monobloc, de telle sorte qu'un déplacement 1 de la selle 2 vers l'avant de la bicyclette (fig.5 et en pointillé sur la fig.1) induise un rapprochement 3 du pédalier 4 vers la roue arrière 10, et vice versa (fig.6 et 1). According to a first embodiment, shown in fig.1,2,5 and 6, the arm 6 is in one piece, so that a movement 1 of the saddle 2 towards the front of the bicycle (fig.5 and dotted on fig. 1) induces an approximation 3 of the bottom bracket 4 towards the rear wheel 10, and vice versa (fig. 6 and 1).
Selon une deuxième forme de réalisation, représentée sur les fig.3 et 4, le bras 6 est composé de deux bras élémentaires 12 et 14 chacun articulé sur le cadre 8, les dits bras élémentaires 12 et 14 supportant respectivement la selle 2 et le pédalier 4 à l'une de leurs extrémités, et étant reliés l'un à l'autre par l'intermédiaire d'une pignonerie 16 à leur autre extrémité, de telle sorte qu'un déplacement 5 de la selle 2 vers l'avant de la bicyclette (fig.4) induise un éloignement 7 du pédalier 4 de la roue arrière 10, et vice versa (fig.3). According to a second embodiment, represented in FIGS. 3 and 4, the arm 6 is composed of two elementary arms 12 and 14 each articulated on the frame 8, the said elementary arms 12 and 14 respectively supporting the saddle 2 and the crankset 4 at one of their ends, and being connected to each other by means of a pinion 16 at their other end, so that a displacement 5 of the saddle 2 towards the front of the bicycle (fig. 4) induces a distance 7 from the crankset 4 from the rear wheel 10, and vice versa (fig. 3).
On notera que le choix entre la première et la deuxième forme de réalisation est déterminée en fonction de la spécificité du cycle, telle que "tout terrain", "route", ou encore "piste" par exemple. It will be noted that the choice between the first and the second embodiment is determined according to the specificity of the cycle, such as "all terrain", "road", or even "track" for example.
Avantageusement, la selle 2 est équipée de moyens de maintien en horizontalité nonobstant un pivotement du bras 6 ; selon une forme préférée de réalisation, les dits moyens de maintien sont constitués d'un parallélogramme déformable, dont le bras 6 et la selle 2 constituent respectivement deux des côtés voisins, les deux autres côtés étant formés par une tringle 18 et par une biellette 20, les extrémités de la tringle 18 étant respectivement articulées sur la selle 2 et sur la biellette 20, celle-ci 20 étant elle même articulée sur le bras 6. Advantageously, the saddle 2 is equipped with means for holding horizontally notwithstanding a pivoting of the arm 6; according to a preferred embodiment, said holding means consist of a deformable parallelogram, of which the arm 6 and the saddle 2 respectively constitute two of the neighboring sides, the two other sides being formed by a rod 18 and by a connecting rod 20 , the ends of the rod 18 being respectively articulated on the saddle 2 and on the link 20, the latter 20 being itself articulated on the arm 6.
De préférence, des moyens de durcissement du pivotement du bras 6 sont constitués par un vérin à gaz 22, représenté sur la fig.2. Preferably, means for hardening the pivoting of the arm 6 are constituted by a gas spring 22, shown in FIG. 2.
Avantageusement, le dit vérin à gaz 22 est équipé de moyens de blocage 28 du déplacement de sa tige 24, et de moyens de commande 30 depuis le guidon 26 de la mise en oeuvre des dits moyens de blocage 28, de telle sorte que le pédalier 4 puisse être immobilisé à une position désirée par rapport à la roue arrière 10. Advantageously, said gas spring 22 is equipped with means 28 for blocking the displacement of its rod 24, and control means 30 from the handlebar 26 for the implementation of said blocking means 28, so that the pedal unit 4 can be immobilized at a desired position relative to the rear wheel 10.
Par exemple, les moyens de blocage de la tige 24 sont constitués par un clapet 28 d'évacuationadmission d'air dans le corps du vérin 22, et les dits moyens de commande sont constitués par un câble 30 de manoeuvre du clapet 28. For example, the means for locking the rod 24 are constituted by a valve 28 for evacuating air into the body of the jack 22, and the said control means are constituted by a cable 30 for operating the valve 28.
On notera que l'invention peut être appliquée à une bicyclette équipée de moyens de variation de vitesse, comprenant habituellement des jeux de pignons et plateaux alternativement reliables entre eux par la chaîne de transmission 32, et que dans ce cas, d'une part les moyens 6 de rapprochement et d'éloignement du pédalier 4 par rapport à la roue arrière 10 peuvent avantageusement participer des moyens de variations de vitesse, et d'autre part les moyens de durcissement 22 du pivotement du bras 6 peuvent judicieusement participer des moyens tendeurs de la chaîne de transmission 32. It will be noted that the invention can be applied to a bicycle equipped with speed variation means, usually comprising sets of pinions and chainrings alternately interconnected by the transmission chain 32, and that in this case, on the one hand the means 6 for bringing the pedals 4 closer and further away from the rear wheel 10 can advantageously participate in means of speed variations, and on the other hand the means for hardening 22 of the pivoting of the arm 6 can judiciously participate in tensioning means for the transmission chain 32.
Bien que l'on ait décrit et représenté des formes préférées de réalisation de l'invention, il doit être compris que la portée de cette dernière n'est pas limitée à ces formes mais qu'elle s'étend à toute bicyclette comportant les caractéristiques énoncées plus haut. Although preferred embodiments of the invention have been described and shown, it should be understood that the scope of the latter is not limited to these forms but that it extends to any bicycle having the characteristics set out above.
